Lambda is a term used in computer programming which refers to an anonymous function or an expression. It is a function which can be passed as an argument to other functions, and can also be returned by another function. In JavaScript, lambda functions are often used for event handlers, callbacks, and other functional programming tasks. Lambda functions can be written using the arrow syntax (=>) which makes them easier to read and write.

Building a sophisticated CodePipeline with CDK in a Monorepo Setup
Many companies are going all-in AWS and thus adopting their complete CodeSuite for their CI/CD processes. However, while CodePipeline is the platform for this process, it may not be the most user-friendly. In a Monorepo setup, it's typical to create multiple CI/CD pipelines for each package. However, there are several caveats to be aware of. For instance, you may encounter scenarios where multiple pipelines get triggered even if you just modified one file, or you may question the need to create multiple branches for each pipeline. In this talk, we provide valuable tips for building a sophisticated CodePipeline using CDK in a Monorepo environment. The techniques discussed in this talk are also transferrable to other CI/CD tools.

Test Time Execution! Why it Can't be Ignored?
For modern agile teams, release velocity is very critical. Unfortunately, one of the biggest bottlenecks for faster release velocity is testing times. Even after teams implement end-to-end test automation, long testing times significantly delay the pipelines. This delay means developers get feedback of their efforts very late, which can snowball, affecting the shipping velocity. Hence test execution time becomes one of the most critical KPIs for any business that wants to ship features faster than the approaching deadlines. LambdaTest helps modern dev teams release faster executing tests faster on a scalable, reliable test cloud.

Troubleshooting your Serverless Node.js doesn't have to be a Pain
AWS ushered in a new landscape for deploying JavaScript applications using Node.js hosted in AWS Lambda, and since then the management simplicity that it provides has made serverless applications and APIs grow exponentially in both popularity and use cases. However, operationally for many starting out, troubleshooting issues can be painful. I'll walk through some techniques to make this easier and provide an evolution of how we can get to a better solution with tips and tools you can use in your serverless deployments right away.

Building Real-time Serverless GraphQL APIs on AWS with TypeScript and CDK
CDK (Cloud development kit) enables developers to build cloud infrastructure using popular programming languages like Python, Typescript, or JavaScript. CDK is a next-level abstraction in infrastructure as code, allowing developers who were traditionally unfamiliar with cloud computing to build scalable APIs and web services using their existing skillset, and do so in only a few lines of code.
In this talk, you’ll learn how to use the TypeScript flavor of CDK to build a hyper-scalable real-time API with GraphQL, Lambda, DynamoDB, and AWS AppSync . At the end of the talk, I’ll live code an API from scratch in just a couple of minutes and then test out queries, mutations, and subscriptions.
By the end of the talk, you should have a good understanding of GraphQL, AppSync, and CDK and be ready to build an API in your next project using TypeScript and CDK.
